Question

two coins are tossed X number of times simultaneously if the probability of having on head is 0.55 where it occurred 275 times then find the value of x.

Answer 1

Answer:

dude here is your answer

Step-by-step explanation:

probability =0.55/total no of  observation.        total no of obervation=275/0.55=500

thus this is the answer

                                                                       

Answer 2

The value of x is 500.

Explanation:

Given : Two coins are tossed X number of times simultaneously  .

Number of favourable outcomes = 275.

Then, the probability of having on head = $\dfrac{275}{X}$         ..................(1)

The probability of having on head is 0.55 .            ....................(2)

From (1) and (2), we have

$\dfrac{275}{X}=0.55\\\\\Rightarrow\ X =\dfrac{275}{0.55}=\dfrac{27500}{55}\\\\\Rightarrow\ X=500$

Hence, the value of x is 500.
